[switch] Leave TextInput running

Text mode is on by default. Calling SDL_StartTextInput() will start the
virual keyboard, but does not allow for a default value. Calling it as
well as switch_start_text_input() will start the keyboard a secound
time.
We still turn TextInput off on other platforms when it's not needed as
it can require additional resources.
